众所周知,砖瓦厂是吃土、耗能大户,而砖瓦粘土和能源是用了不可再生的宝贵资源.盐都县地处苏北平原,属国家重要粮棉生产基地.全县有24家砖瓦轮窑厂,如果砖厂每生产1万块普通砖比国家规定多用1t土,那么一年下来一座轮窑厂(18门)生产红砖2000万块的话,就多耗用粘土2000t,为社会少提供普通红砖80多万块,砖厂本身年降低销售额14.58万元,年耗煤电费用增加1.2万元,按挖深5m计算,毁坏浪费农田4亩,国家集体少收粮食0.8 万斤.由此看来,砖瓦轮窑厂节土节能工作好坏,不仅关系到窑厂自身的经济效益,更重要的是关 As we all know, brick and tile plants are large soil-consuming and energy-consuming households, and brick clay and energy are used as precious resources that are not renewable. Yandu County is located in the northern Jiangsu Plain and is a national important grain and cotton production base. There are 24 counties in the county. For a brick and tile kiln factory, if a brick factory produces 10,000 ordinary bricks more than 1 tonne of soil per national rule, then if a brick kiln factory (18 gates) produces 20 million red bricks a year, it will consume 2000 tons of clay. Providing less than 80,000 pieces of ordinary red bricks for the society, the bricks factory reduced sales by 145,800 yuan a year, annual coal and electricity costs increased by 12,000 yuan, calculated by digging 5 meters, destroyed 4 acres of wasted farmland, and the state collectively collected less food. 0.8 kilograms. It seems that the energy efficiency of soil and clay in the brick and tile kiln factory is not only related to the economic benefits of the kiln factory, but more importantly, it is related to
